Let = the man's age now
Let the son's age now
-------------------------------
I'll work backwards on this.
" his son will be two years from now"
His son will be
--------------------------------
" when the father was twice as old as"
When the father was:

--------------------------------
"As old as his son was"
The difference in their ages will always be

So, at that time, the son's age was:

--------------------------------
"The man is three times as"
That is talking about the present age of the man

--------------------
Also given:

Multiply both sides of this equation by
and add the equations

---------------------

and

The man is 39
The son is 16
--------------------
check:
" his son will be two years from now"
His son will be
----------------------------------
" when the father was twice as old as"
When the father was:

----------------------------------
"As old as his son was"

---------------------------------------
The father is 3 times that age:

OK
